What do I do if the top heavy duty handle hits the back of the monitor and can't tighten further?

The heavy duty handle has a pull out feature built into the handle for repositioning the handle. When handle is close to the monitor back and you still need more tightening, simply pull out on the handle and reposition to tighten further. Once the handle is in the right position for full tight, you should not have to make that adjustment again when adjusting tilt on monitor. We chose this handle in order to maximize lock down torque.
